How and why we should think about testing and tips on what to test, and things to monitor.

Exception and Error Handling

Properly handle exceptions and errors to prevent crashes and provide meaningful feedback to users

Log errors to an external system to allow us to find out when there are issues with our code.

Logging, Monitoring and Auditing

Implement comprehensive logging to track the behavior of your software. Set up monitoring and alerting to proactively identify and address issues. Maintain audit trails for critical actions to ensure accountability.

Health and Performance Checks

Implement health checks to verify the status of your application. Use monitoring tools to track performance, resource utilization, and error rates during and after deployment.

Regularly profile your code to identify performance bottlenecks. Optimize critical sections and use appropriate data structures and algorithms.
